The fifth day without food! Unbelievable. Only a few months ago I was feeling rather bad after skipping a meal, and a thought about fasting for a few days would have been inconceivable. Actually, it is quite amazing how body is able to function with no external energy sources. I cannot say I feel great, but I definitely feel acceptable, and feel no hunger.
Today was rather similar to yesterday. I tried to run in the morning (without children) and could not make myself to, so I just walked. I thought that I was walking slightly faster than yesterday, but I still was quite tired at the end. The skin on fingers and the tongue coating are also slightly better.
I noticed these days that I get rather dizzy when rising abruptly. I’ve read about this effect in the literature; it is caused by lowered blood pressure when fasting.
Update: In the evening, I ran a little bit with my wife. I would’ve never even started without her! I also got some unexepected bowel movements
